tried a 60 series tire, ?? salt build up may be more of a problem than tech inspection
Yes, salt buildup and tire growth is what I am concerned about and questioned if there is a rule or minimum recommendation at the scrutiny.
I got numbers of 1/2" and 3/4" To me that sounds awful small, but I have no experience.
It's not my bike and the same tire size wasn't available for some reason.
I tried to move this topic to the perhaps more appropriate "BUB rules question" but ended up with a duplicate, sorry for that.
